@Bibibia I think you are right. Men don't really wear their hearts on their sleeves but she does it so blatantly when she is around him. So I think he'll start figuring it out that she is a woman. But I don't think he'll start a triangle. I think he would say duty comes first and as long as you do your duty that's all that matters and he'll keep her secret like a good little boy till he is asked directly by the emperor if she has any secrets or if she is a woman.
